FASTENING OR SECURING MEANS;

,iar w J. Trroinsoma citizen,v of; the .Unitedrstateaand ,a resident of-Gantomcountyof Norfolk and Commonwealth of Massachusetts, have inventedan Improvement in Fasteningsor Secur ng Means, of v which the following descrlptlon,

;: in connection with-the accompanying drawings, is a specification, like characters on the drawings representing like parts.

f My inventionirelates to fastening or securi ng. .;means ,for cords, ropes and the I like.

Whileithis inventionis adaptedfor use ina great'variety ,ofv cases, signed;E for,-use,1n connection Wlth ,a skindrying frame for the purpose of securing to the frame the toggle 1 cords which are used tojstretch and dry skinsEiOr hides during theintreatmentto produce certain kinds ,of leather, 1 as patent or enamel leather.

Referring .to the drawings of onev embodi- 1ment of my invention illustrated and described iinthis-application: 1 Figure 1 is a plan of said invention applied to a conventionalform of skin stretching-gimme; a 1 r a $1 w s Fig, 2.is,a detail, ,on; an enlarged scale, of the fastenin'gmembers, showing one meth'o'd J of using the, same;

ingfromthe right,ithe staple being omitted. Referring to'Figs." "-1 and 2, a frame or ,-ba se l,- of suitable size and. material as wood,

.is shownprovlded witha series of fastening -,dev;iees or toggle fasteners, made preferably from; ;a piece 10f Wire 01'11101'1,

according to the size required, fashioned, to form a plusrality of toggle gripping, open end, loops 3. The loops herein are shown as positioned at 3 angle relative to the longitudinal strips, comprising the frame 1,

to provide a more ,convenlently operable fas- Qtener, as will be pointedout more particu- .:.1a yzl n.- a

Each loop preferably consists of an an- ;chor'edbar A, and bar. 15, the anchored bar being secured conbyea staple 6, to the frame it is particularly -de-' an unanchored or free member. The two bars forming each loop are, 1-;f0r convenience, preferably inclined slightly toward each other, so that each loop isUsomewhat V shaped info-rm.. For convenience in assembling, the bar A} is offset downwardly somewhat at 7 Fig. 4:. This enables the. workman to see at a glance where thestaple shouldbe inserted, and also being naturally driven more or less into the wooden frame when the staple is inserted, the offset position answers as an additional anchorage for the loop member.

- Application filed July 23, 1917. Serial No. 182,186.

In use, the skin 8 havlng been placed within the; frame 1, a series .of toggle fasteners 9 of any approved style, are positloned upon the edge of the skin at suitable points. The. cordsv 10 from the toggles are 7 carried preferably as directly as possible to the nearest fastener 3, although insome instances, to stretch and hold the skin prop- .erly, it is desirable'to carry the cordsangularly to a fastener.

It is common at. his time, to use a frame provided with, fasteners in the form of closed loops, each barofeach loop being securely anchoredto the frame. This fastener is positioned so that the loops extend laterally at right angles to the frame member. This type of fastener is objectionable and unsatisfactory.because, both bars of the loop being anchored to the frame, they do not retain sufficient resiliency, after short use, to engage; the toggle cord securely. -The cord, being, drawn tightly beneath the loop end, is, in ashort' time, owing-to the;weari'ng loop end, brought up against the staple the cords become somewhat smooth from wear and the loop loses somewhat its resiliency, frequently the cords slip from beneath the loops and become slack and the stretching of the skin is not effected properly. I V

To avoid this difficulty I have conceived the idea of anchoring one bar 4 of the loop, as stated, while permitting theother bar 5 of the cord or the lessened resiliency of the carried beneath the loop with less difliculty thanis the case where the loop is positioned at substantially right anglesto thestrip, as

there is less danger of the cord slipping up over the loop where the cord engages it angularly, rather than in a parallel direction.

In use the cord is first passed beneath the outer end of the anchored bar 4: where this bar, with the strip 1, forms a bight which may be indicated a, and the loop presses the cord against the strip -1; the cord is then carried beneath the adjacent, outer end of the free bar 5 which also, by virtue of its own resiliency, and because it is positioned upon and firmly against the strip 1, engages it and again, forms a second bight, and presses upon the cord to the full extentof the resiliency of the bar, unhampered and unrestrained by any action of any anchoring member. These two biting engagementsby the fastener of the cord 10 will often give the necessary secure fastening of the cord. However, if desired the cord may be next carried over the bar 5 thus holding the bar firmly down upon the cord beneath, it at bight b, and the cord may be neXt carried again beneath the inner end of the-free bar 5 where another bight 0 is formed. Here pressure by the bar 5, unrestrainedand unlimited by any anchoring member, is again imposed on the cord and finally it may be carried beneath the inner end of the neXt anchoring bar 4 to form bight (Z where it receives the full holding effect of that bar.

The result of the foregoing action is that the cord, by being passed under the first loop 3 receives the biting effect of two bars,one ofwhich is anchored, and if carriedbeneath the inner endof the free bar and beneath the end of the adjacent anchored bar, it has imposed upon it the additional biting effect of the inner end of anchored bar f and inner end of the adjacent unanchored bar 5, the bar 4 being held firmly down in'position by the cord 10, itself carried over the'same substantially midway between its inner and outer ends. The bites of the free bar 5 upon the cord 10 are particularly effective, as stated, because the bar is free toeXert its entire resiliency upon the cord unhampered by the presence of any anchoring member.

In cases where the toggle cords do not eX- tend at substantially right angles to the frame member 1, the full biting'efiectis obtained however. Even though the anchored bar 4 loses its resiliency to some, extent through continued use, as is the case with fasteners in common use to-day, the free bar will not be so affected, and will preserve its resiliency for effective action indefinitely.

In Fig. 3 a detail of a modified form of fastener is shown where theinner ends of the fasteners are connected by straight instead of curved lines. I

In some respects the retaining of the body of the wire2 in the form of a straight connecting member for the loops, instead of curving it as in Figs. 1 and2, possesses an advantage; as sometimes it; seems to-be easier to draw the cord 10 beneath the-wirewhen fashioned as inF ig. 3-, becausethew-irepre sents in some cases an angular instead of a curved edgeto the-cord-.

In either case the body of 'thewire co'nf necting'the loops is preferably raised" slightly above the'framemember 1 as in the caseof the closed'loop end-show-nin Figs. 1 and 2.
